Tech stocks continued their downward slide from Wednesday after President Donald Trump announced sweeping tariffs, costing several huge Northwest billions in market value.

Share prices for two of the most valuable companies in the world, Seattle-based Amazon and Redmond-based Microsoft, fell Wednesday in after-hours trading. Once the markets could gauge the news on Thursday, those companies continued to fall. Amazon had fallen 7% as of Thursday morning while Microsoft dipped another 1%.

The Seattle area’s other tech companies aren’t faring well either. Expedia tumbled 7% on Thursday, and Zillow slipped 3%. Meta, Google and Salesforce aren’t based in the Puget Sound region but all three have sizable engineering hubs in the area. They’d all fallen 6%, 3% and almost 5%, respectively.

T-Mobile saw a 1% gain, erasing the Wednesday loss.

Retail companies in the Puget Sound region were also hammered by Wall Street Thursday morning. Nike and Columbia, both based in the Portland area, each fell by 11% Thursday morning following steep drops Wednesday afternoon. With harsher tariffs on Asian countries, apparel companies are particularly vulnerable due to their reliance on suppliers in Vietnam, China and Indonesia.

Two other Seattle-based companies that rely on imported goods, Starbucks and Boeing, fell 11% and 7%.
